I BY 3 a] i Q 1115 ATTORFVEY Patented July 18, 1933 UNITED STATES Jrssn M. WHITE, or PHILADELPHIA, PENNSYLVANIA counur'r FITTING Application filed December 11, 1931. Seria1 No. 580,476.

This invention relates to conduit fittings,

and has for an object to provide a fitting especially adapted for use with loom to retain such loom in the ferrule constituting in part the fitting.

The particular fitting most especially aimed at in the present instance is such a fitting as is employed at the end of loom, or the like, for carrying wires and finds one of its utilities in the connection of wires with headlights or other lights of automobiles.

It has been recognized that loom is an ideal conduit for use in such places, but it has heretofore been found impossible, or at I least impracticahto make the necessarily permanent connection between the loom and the metallic ferrule which forms the fitting which is associated with the complementary fitting employed upon the light housing, or other parts where the fittings are to be interconnected.

The object of the invention is therefore to provide a permanent connection between a 26 loom conduit and a metallic ferrule so that the combination shall form a conduit fitting of the type referred to.

The invention therefore, comprises a metallic terminal ferrule of substantially the 30 usual and ordinary type employed in such installations and with a loom fitted into the smaller or reduced end of the ferrule, with means properly expanding the end of the loom enclosed within the ferrule so that the reduced or inturned end of the ferrule will bear against a shoulder of the loom held in such expanded position by an inner expander.

The drawing illustrates an embodiment o of the invention and the views therein are as follows:

Figure 1 is a view in side elevation of the fitting,

Figure 2 is a longitudinal sectional view, 5 taken on line 2-2 of Figure 1,

Figure 3 is a transverse sectional view, taken on line 33 of Figure'2,

Figure 4 is an end view of the fitting, Figure 5 is a longitudinal diametrical sec" 50 tional View of a modified type of expander,

- and and permanently retain the loom in proper Figure 6 is a sectional view, taken on line 66 of Figure 5.

Like characters of reference indicate corresponding parts throughout the several views.

The ferrule 10, employed in the present case, is substantially the usual and ordinary ferrule employedfor connection with the fitting of a headlight or other housing, lugs 11 being employed in the usual manner for association with joints of the bayonet type. Opposite the end, carrying the lugs 11, the ferrule is reduced to the taper. The insulating block 14 is of the usual type employed, with contacts 15. As shown at F igure 4, three of these contacts are exhibited, but the number may be greater or less as occasion makes necessary; The conduit 16 is of the usual and ordinary loom type, and o in the type shown at Figure 2, the end of the loom which is inserted into the reduced part 12 has inserted a tapered sleeve 17 which expands the loom at the locus of such sleeve to a tapered form; A 76 As shown, this sleeve 17 is provided with an outurnedfiange 19, but this flange is relatively unimportant, the importance being merely to properly center the loom relative to the ferrule. so

As shown at Figure 5, the loom 16 is provided with a ring 20 which is merely expanded within the loom, forming an equatorial rib 21which bears against the lip 13 of the ferrule which is preferred in this embodiment. f

In operation, of course, the sleeve 17 or the ring 20 will be inserted into the end of the loom to expand the loom at the locus of the ring or sleeve. This may be done before the loom is introduced into the ferrule 10, and then the loom threaded through from the larger to thersmaller part, or it may be inserted through the smaller part to extend beyond the larger part, and the expander employed in that position. In any instance, when the loom is draw inwardly into the ferrule,'the taper formed by the sleeve 17 or the shoulder formed by the ring 20 will engage against the reducedpart of the ferrule having a tapered reduced part, a loom fitting normally within the reduced part, and a ring within the loom expanded therein to expand the loom locally to form an external rib contacting with the reduced part of the ferrule.

2. A conduit fitting comprising a ferrule having an inturned lip, a loom fitted within the, annulus of the lip, and a ring inserted Within the loom and expanding the loom l locally forming a circumferential rib in contact with the lip.
